The timer callback may still be running and can\nrearm itself, resulting in a use-after-free.\n\nUse timer_shutdown_sync() to wait for the callback and prevent further\nrearming. Do this unconditionally because ss_en may be changed after\nthe timer is armed.\n\nMove timer_setup() into init_realtek_cr() so the timer is initialized\nbefore any failure path can invoke the destructor.\n\nFound by static analysis.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/4ffee1aebb0c0ffcda9faffd17834ea9b00d42cc","https://git.kernel.org/stable/c/524d4257f741cd95eb85e2817c9c890928fcfef7","https://git.kernel.org/stable/c/7c4e2f964c65dea4ea22386799d5fb10ef1e3e54","https://git.kernel.org/stable/c/c1e7e35100efffba7c9e1dfa76519d6cd323ba3d","https://git.kernel.org/stable/c/cae9dbba6adae21a04a3bd045e07b489847ff2c6"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-90029","score":0.00192,"percentile":0.08783,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
